The wildlife exemption in Hill County

Hill County land qualifies for the same wildlife management valuation used across Texas - same statute, same forms - but the practices that succeed here are pure Blackland Prairies. Get the regional details right and the tax side takes care of itself.

The Blackland Prairies run in a crescent from the Red River through Dallas to San Antonio - deep, fertile black clay that once grew tallgrass prairie and now grows subdivisions and row crops. Less than one percent of the original tallgrass remains, which makes prairie restoration on Blackland properties both ecologically important and highly credible with appraisal districts.

Deer populations in the Blacklands concentrate along creek corridors and remaining woodlands; many successful wildlife management programs here focus on grassland birds and pollinators rather than deer alone - a fully qualifying approach under 1-d-1. Typical target species for Hill County plans include white-tailed deer, bobwhite quail, grassland songbirds like meadowlarks and dickcissels, waterfowl on stock tanks, and native pollinators. The recurring habitat challenges - near-total loss of native tallgrass prairie, johnsongrass and KR bluestem invasion, and intense development pressure - are what a good management plan turns into qualifying work.

On the ground in Hill County

Hillsboro, I-35, blackland and the edge of the Cross Timbers. Hill County sits on the western edge of the Blackland Prairie, where crop fields and dark soils begin to meet limestone and more wooded country. A wildlife plan can restore native grass/forbs, protect creek corridors and retain appropriate woody edge without letting brush swallow prairie habitat. For a Hill County wildlife exemption, that prairie-to-Cross-Timbers transition is useful local context and explains why tract-level planning matters.

Hill County lies in the Blackland Prairies and is assigned to TPWD's Blackland Prairie wildlife-use appraisal region - the legal map that sets the reduced-tract acreage rule below.

Is there an acreage minimum in Hill County?

Did the tract get smaller since January 1 of last year?

No ➔

There is no wildlife acreage test in Hill County at all. Whatever the size, file Comptroller Form 50‑129 with a PWD‑885 plan. A 7-acre tract that already carried 1‑d‑1 (ag exempt) and was never split can convert with no penalties.

Yes ➔

The Hill County appraisal district has published its figure. The legal minimum land requirement is 12.5 acres (92%). Wildlife management property associations: 10 acres (90%).

How it works here

Hill County follows the statewide 1-d-1 framework (Texas Tax Code §23.51(7)); the local variables are your appraisal district's filing habits and the Blackland Prairies intensity standards:

  • Start from an existing ag or timber valuation. Wildlife management is a conversion of qualified open-space land - check eligibility if your status is unclear.
  • File a wildlife management plan (TPWD form PWD‑885) with the Hill County appraisal district, attached to Comptroller Form 50‑129, between January 1 and April 30. What goes in the plan →
  • Perform at least 3 of the 7 practices each year at Blackland Prairies intensity levels - see the local examples below.
  • Document everything - dates, photos, quantities. When the chief appraiser requests an annual report (PWD‑888), you'll answer with records, not recollections.
  • No minimum acreage applies unless your tract got smaller since January 1 of last year. If it did, Hill County's figure is covered above - the district picks one number for the whole county, and the plan is still the application either way.

The 7 practices, Blackland Prairies-style

These are the kinds of activities appraisal districts in the Blackland Prairies recognize as real management - your plan picks at least three. The Blackland Prairies region guide covers the species, habitat problems and intensity standards behind them.

1

Habitat control

Restoring native tallgrass species (big bluestem, Indiangrass, eastern gamagrass), controlling johnsongrass and KR bluestem, and managing riparian woodlands along creeks.

2

Erosion control

Grassed waterways in old crop fields, gully repair in the erosive clay, and buffer strips along creeks to keep the black soil in place.

3

Predator control

Feral hog control along creek bottoms, red imported fire ant management in nesting habitat, and cowbird trapping to protect prairie songbirds.

4

Supplemental water

Wildlife-friendly stock tank management with gradual slopes and emergent vegetation, small shallow wetlands for migrating shorebirds, and rainwater collection for guzzlers.

5

Supplemental food

Native forb and wildflower plantings for pollinators and seed-eating birds, milo and sunflower strips for dove, and managed grazing deferment to build seed and insect abundance.

6

Providing shelter

Establishing thicket mottes of native plum and sumac for quail, leaving field borders in tall cover, and installing nest boxes for bluebirds and kestrels.

7

Census counts

Point-count songbird surveys in spring, fall covey counts, incidental deer camera surveys, and annual photo points to document prairie recovery.

Filing & the appraisal district

DateWhat happens in Hill County
January 1Valuation date - land is judged on its use and qualification as of this day.
Jan 1 – Apr 30File Form 50‑129 with your PWD‑885 plan at the Hill County appraisal district (Hillsboro).
After Apr 30Late applications accepted until the appraisal roll certifies, with a 10% penalty on that year's savings.
On requestThe chief appraiser may require a PWD‑888 annual report - many districts ask annually. Keep logs so the answer is one click away.

The Hill County appraisal district is headquartered in Hillsboro. For current mailing addresses, phone numbers, and any locally adopted wildlife-use ratio, use the Texas Comptroller's county directory - and confirm details before filing; districts occasionally adjust procedures year to year.

The cost of letting it slip

Losing qualification means market-value taxes going forward - and if the land's use changes to non-agricultural, rollback taxes: the previous three years of tax savings, recaptured in one bill. On typical Hill County acreage that's easily five figures. How rollback works →

Hill County questions

Hill County wildlife exemption FAQ

The questions Hill County landowners ask most - answered against this county’s appraisal district and the Blackland Prairies standards its plans are judged by.

How many acres do you need for a wildlife exemption in Hill County?
For most tracts, there is no minimum at all. Hill County applies no acreage test to wildlife management use unless your tract was reduced in size since January 1 of the preceding year. If it was, the Hill County appraisal district applies the figure it has adopted: a wildlife-use requirement of 12.5 acres (92%), stated as a ratio rather than an acreage - the district applies it to your tract. The district sets 10 acres (90%) for land in a wildlife management property association. A tract that was never split can convert at any size, so long as it already carries a 1‑d‑1 (ag exempt) valuation. Source: Hill County Appraisal District Agricultural Guidelines, January 2024.
What is the wildlife exemption filing deadline in Hill County?
April 30. The window opens January 1 and closes April 30 - file Comptroller Form 50‑129 with a TPWD PWD‑885 wildlife management plan attached at the Hill County appraisal district in Hillsboro. Miss it and the district still accepts a late application until the appraisal roll certifies (typically mid-July), but with a 10% penalty on that year’s tax savings. One trap catches new owners every year: buying land that already holds the valuation does not carry it over to you - you have to file your own application.
Do I need an existing ag exemption to get a wildlife exemption in Hill County?
Yes. Wildlife management is a qualifying use within the 1-d-1 open-space valuation, not a separate exemption - so the land has to already carry an agricultural or timber productivity valuation on the day you convert. If it does, converting changes the qualifying activity and nothing else: the productivity value carries over from your previous ag category, so your tax bill does not move. If the land lost its valuation, you would requalify the ordinary way first - agricultural use for 5 of the preceding 7 years - and then convert. The conversion playbook →
Which wildlife management practices qualify in Hill County?
Any three of the seven named in Texas Tax Code §23.51(7): habitat control, erosion control, predator control, supplemental water, supplemental food, providing shelter, and census counts. The list is statewide, but the standard you are judged against is regional - Hill County is Blackland Prairies country, so the Hill County appraisal district expects work sized to Blackland Prairies intensity levels and aimed at the problems that actually limit wildlife here: near-total loss of native tallgrass prairie, johnsongrass and KR bluestem invasion, and intense development pressure. Habitat control, supplemental water, and census counts are the most common opening three. See what each one looks like here →
What species should a Hill County wildlife management plan target?
Whatever you name, it has to be indigenous - Texas Tax Code §23.51(7) qualifies land used to sustain a breeding, migrating, or wintering population of native wild animals, and that is the species test that actually decides qualification. In the Blackland Prairies, plans are usually built around white-tailed deer, bobwhite quail, grassland songbirds like meadowlarks and dickcissels, waterfowl on stock tanks, and native pollinators. Deer populations in the Blacklands concentrate along creek corridors and remaining woodlands; many successful wildlife management programs here focus on grassland birds and pollinators rather than deer alone - a fully qualifying approach under 1-d-1. Introduced species are the common trap: exotics like axis deer or blackbuck may live on the property, but managing for them (alone) earns you nothing toward your three practices - so confirm every species you name in the plan is native to Texas before you file.
Does Hill County require a PWD-888 annual report every year?
The chief appraiser may require one whenever they ask - that is the statutory standard, and many Texas districts ask annually or on a review cycle. The practical answer is to assume it is coming: keep dated records, photos, and quantities for every practice as you go, and the report is a formality instead of a scramble. Landowners rarely lose a valuation because the work was not done; they lose it because the work could not be proven. What a strong PWD‑888 looks like →
Will switching from cattle to wildlife trigger rollback taxes in Hill County?
No. Rollback under Texas Tax Code §23.55 is triggered by a change to a non-agricultural use - developing, paving, or subdividing the land. Moving from grazing to wildlife management is a change of use within 1-d-1, so the valuation continues uninterrupted and no recapture is owed. What does carry risk is letting the land go idle: land quietly used for nothing agricultural can be treated as having changed use. A documented wildlife plan is precisely how you stay out of that gray zone. How rollback works →
Who approves the wildlife exemption in Hill County - TPWD or the appraisal district?
The appraisal district. The Hill County appraisal district’s chief appraiser reviews your Form 50‑129 and PWD‑885 plan and decides whether the land qualifies, the same as for any agricultural application. Texas Parks & Wildlife publishes the forms and the ecoregion guidelines your plan should match, but it does not approve individual properties and has no vote on your valuation. The district is headquartered in Hillsboro; current contact details are in the Texas Comptroller’s county directory.
